How to install a basin tap?

Installing a basin tap is a straightforward DIY project that can instantly refresh your bathroom. With a few basic tools and some patience, you can easily handle this task yourself. Here is a simple, step-by-step guide to help you get the job done.

What You’ll Need

  • Adjustable spanner or basin wrench

  • Plumber's tape (PTFE tape)

  • Flexible tap connectors (usually included with new taps)

  • A bucket and old towels

  • Safety goggles

Step 1: Turn Off the Water Supply

Before doing anything, turn off the water supply to your bathroom.

  • Look for isolation valves on the pipes beneath the sink and turn them clockwise using a flathead screwdriver.

  • If you don't have isolation valves, turn off your home's main stopcock.

  • Open the tap to drain any remaining water in the pipes.

Step 2: Remove the Old Tap

  1. Place your bucket and towels under the sink to catch any stray drips.

  2. Unbolt the flexible hose connectors attached to the old tap using your adjustable spanner.

  3. Unscrew the retaining nut underneath the basin that holds the tap in place.

  4. Carefully lift the old tap out from the top of the basin and clean around the mounting hole.

Step 3: Prepare the New Tap

  1. Screw the flexible supply hoses into the base of your new tap by hand until finger-tight, then give them a gentle quarter-turn with a spanner (do not overtighten).

  2. Insert the threaded metal stud into the base of the tap.

  3. Fit the rubber washer/O-ring onto the bottom of the tap base. This seal prevents water from leaking under the sink.

Step 4: Fit the New Tap

  1. Guide the flexible hoses and the threaded stud down through the hole in the basin.

  2. Position the tap so it sits straight and faces forward.

  3. From underneath the sink, slide the rubber washer and the horseshoe-shaped metal plate onto the threaded stud.

  4. Screw on the retaining nut by hand, then tighten it with a spanner or basin wrench until the tap is firmly anchored to the basin.

Step 5: Connect the Water Pipes

  1. Connect the flexible hoses to your hot and cold water supply pipes. (Make sure you connect hot to hot and cold to cold).

  2. Wrap a few turns of PTFE tape around the male threads of the supply pipes before attaching the nuts to ensure a watertight seal.

  3. Tighten the compression nuts securely, taking care not to twist or kink the flexible hoses.

Step 6: Test for Leaks

  1. Wipe down all connections beneath the sink with a dry towel so you can easily spot any fresh water droplets.

  2. Slowly turn the main water supply (or isolation valves) back on.

  3. Turn on the new tap and let the water run for a minute.

  4. Check underneath the sink for any signs of dripping around the connections. If you notice a slow leak, give the loose nut a minor turn until it stops.
